Research on Control Scheme of Subspan Oscillation in 6-Bundle Transmission Line

In this paper, penalty function method is applied for the 6-bundle spacer optimal arrangement to inhibit subspan oscillation. Based on the arrangement, 3-bundle spacers are installed in 6-bundle transmission lines. Analysis of aerodynamic variation of conductor and damping effect of the control scheme is conducted by the foundation of finite element model. Besides, assessment is carried out with transmission line on-line monitoring system to prove the efficiency.
